The result to the factorization of the polynomial is 3x (x + 10) (x - 10).
Polynomial FactorizationFactoring polynomials involves utilizing prime factorization to break the given polynomial down into a product of two or more polynomials. Polynomials can be readily simplified by factoring them.
Writing each term of the longer expression as the product of its elements is the initial step to factorization polynomials.
= 3x³ - 300x
= 3x(x²) - 300x
= 3x(x²) - 3x(100)
= 3x(x² - 100)
= 3x(x² - 10²)
Since both terms are perfect squares, factor using the difference of squares formula, a² − b² = ( a + b ) ( a − b );
where
a = x and b = 10= 3x (x+10) (x−10)

You started a savings account by depositing $4,200. The savings account earns 2.1% APY, compounded monthly. What was the balance in the account after 2 months?
1=Prt
4214.7 is the balance in the account after 2 months .
What does compound and simple interest mean?
A fixed proportion of the principal amount borrowed or lent is what is known as simple interest and is paid or received over a given period of time.
Borrowers are required to pay interest on interest in addition to principal because compound interest accrues and is added to the total amount of interest from earlier periods.
P = $4200
R = 2.1% = 2.1/100 = 0.021 =
T = 2 month = 2/12 = 1/6
I = PRT
= 4200 * 0.021 * 1/6 = 14.7
Amount = P + I = 4200 + 14.7 = 4214.7

The missing angle is approximately 108.5 degrees.
What is the law of sines?Law of sines is a trigonometric formula that relates the sides and angles of any triangle. Specifically, the law of sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in the triangle.
Using the law of sines:
sin(128°)/15 = sin(x)/12
Multiplying both sides by 12:
sin(x) = 12sin(128°)/15
Taking the inverse sine of both sides:
x = sin^-1(12sin(128°)/15)
x ≈ 108.5°
Therefore, the missing angle is approximately 108.5 degrees.

As Bin is driving her car, she notices that after 1 hour her gas tank has 7.25 gallons left and after 4 hours of
driving, it has 3,5 gallons of gas left in it.
(3) Represent this information as two coordinate
pairs in the form (1, g), Where A is the
number of hours driven and g is the gallons of Gas left
Bin had 7.25 gallons of gas to start with using the unitary method.
Unitary method is a problem-solving technique that involves finding the value of one unit and using it to calculate the value of other units. In this case, we will use unitary method to find the number of gallons Bin had to start with.
Firstly, we need to find the rate of gas consumption. The slope of the line, which is the change in the gas level over time, gives us this information. Since the slope is -1.25, this means Bin is losing 1.25 gallons of gas per hour.
Next, we need to find the total time Bin has been driving. From the problem, we know that after 1 hour, she had 7.25 gallons left, and after 4 hours, she had 3.5 gallons left. This means that she drove for 3 hours (4-1).
Using the unitary method, we can calculate the total amount of gas Bin had to start with. We know that she lost 1.25 gallons of gas per hour, and she drove for 3 hours. Therefore, she lost a total of 3.75 gallons of gas during the trip.
To find the initial gas level, we need to subtract the amount of gas she lost from the gas level she had at the end of the trip. This gives us:
Initial gas level = Gas level at end of trip + Gas lost during the trip
Initial gas level = 3.5 gallons + 3.75 gallons
Initial gas level = 7.25 gallons

robin is twice as old as earl and adam is 8 years younger than earl. in 6 years robin will be three times as old as adam. find their present ages
The present age of Earl is 12 years, Robin is 24 years and Adam is 4 years old.
Let us consider the present age of Earl to be x years.
According to the given question, the present age of Robin is twice that of Earl = 2x
And since it is given that Adam is 8 years younger than Earl, then his age
= x - 8
After 6 years, the age of Earl will be x + 6
Robin's age will be = 2x + 6
Adam's age will be = x - 8 + 6 = x - 2
According to the given question, Robin's age will be thrice the age of Adam.
Hence, 2x + 6 = 3 (x - 2)
⇒ 2x + 6 = 3x - 6 ⇒ 6 + 6 = 3x - 2x ⇒ 12 = x
Thus, the present age of Earl is 12 years,
Robin's age = 2x = 2 x 12 = 24 years
Adam's age = x - 8 = 12 - 8 = 4 years

The standard form of the equation of the quadratic function is y = -1/8x^2 + 1/4x - 41/8
How to find the standard form of the equation of the quadratic functionFrom the question, we have the following parameters that can be used in our computation:
(h, k) = (1, -5)
(x, y) = (5, -7)
A quadratic function is represented as
y = a(x - h)^2 + k
So, we have
y = a(x - 1)^2 - 5
Given that
(x, y) = (5, -7)
We have
-7 = a(5 - 1)^2 - 5
This gives
16a = -2
So, we have
a = -1/8
Recall that
y = a(x - 1)^2 - 5
So, we have
y = -1/8(x - 1)^2 - 5
Expand
y = -1/8(x^2 - 2x + 1) - 5

What is a composite figure?
A two-dimensional figure built up of fundamental two-dimensional shapes like triangles, rectangles, circles, semicircles, etc. is known as a composite shape or composite figure. To get the area of a composite shape, first determine the individual areas of every component. The total of the individual regions will then represent the area of the composite shape.
From the figure, we can see that from a big rectangle, 4 small identical squares of side 1m are cut from each corner.
We are asked to find the area of the rest of the rectangle which makes the composite figure.
W first find the area of the original rectangle.
Its length = 5 + 1 + 1 = 7 m
Its breadth = 2 + 1 + 1 = 4 m
So the area of the rectangle = length * breadth = 7*4 = 28 m²
Now the side length of the square = 1 m
Area of one square = 1*1 = 1m²
So are of four identical squares = 4 * 1 = 4 m²

Knowing the value of p tells one that option b. whether there is statistical significance.
The concept of probability, which is a measure of the likelihood of an event occurring. It is an essential tool in statistics, and it helps us make informed decisions based on data.
Now, let's dive into the answer to the question. Knowing the value of p tells us about the statistical significance of our results. In statistical analysis, we often conduct hypothesis tests to determine whether a particular effect is significant or just occurred by chance.
The p-value is the probability of observing the results we obtained under the null hypothesis, assuming that the null hypothesis is true. The null hypothesis is the default assumption that there is no significant difference between groups or means.
If the p-value is low, say less than 0.05, we reject the null hypothesis and conclude that there is a significant difference between groups or means. On the other hand, if the p-value is high, we fail to reject the null hypothesis, and we cannot claim that there is a significant difference between groups or means.
To give an example, suppose we conducted an experiment to test whether a new drug reduces blood pressure. We would have a control group that receives a placebo and a treatment group that receives the drug. We measure the blood pressure of both groups and compute the p-value. If the p-value is less than 0.05, we would conclude that the drug is effective in reducing blood pressure.

If 7 book cost rs 300 than 5 same books find the cost of a book
When the cost of 7 books is equal to Rs 300 more than the 5 same books then the cost of a single book is equal to Rs 150.
Let us consider Rs 'x' be the cost of a single book .
Equation to represents the given expression 7 books is equal to Rs 300 more than the 5 same books is :

⇒ 7x -5x = 300 + 5x - 5x
⇒ 2x = 300
Divide both the side by 2 we get,
⇒ 2x / 2 = 300 / 2
⇒ x = Rs. 150
